20 Further: objects of myinvention-comprise the locating. of theabrading orxparingmech- 'anism at a. relatively low; elevation wherebylow' vibration is assured, and. easy access in charging and dischargingmay be had, While the'motorgan-d driving'means are arranged at a higherand rear position so as to'form no bs truction and permit free accessto. the operative or Working part-s; andalso in providing an organizedmachine in which Water :30 may be freely used during itsoperation'without 'danger to the driving or motivepower.

hly object is also to provide a light running machine in'thattherotating abrading disk and shaft therefor are suspended on ball 5bearings and in a manner that the bearings are protected "fromobjectionable contact with Water.

With the above and. other objects in View, the nature of'vvhich Will bemore fully under- 4 stoo dfromthe descriptionhereinafter, the

invent-ion consists in the novel construction of vegetable paringmachine, as -hereinafter more fully described and defined in the claims.

45 Referring to the drawings Fig. 1 is afront elevation of my improvedparing machine Fig. 2 is-a sect-ional planview taken on line 2-2 of Fig.4 Fig. 3- is a plan view of:the machine; FigAL-is-a verticalsection'ta-ken on line 4-4 of Fig. 3; Fig. '5 is a vertical section ofthe lowerbearing for the operative shaft of-the' abrading disk; andjFigt is a vertical section corresponding toEFig. 5 but showing amodified construct-ionthereof.

2 is apedestal or floor baseandupon-it is "securedthe central hub 3madelintegralvvith a circular inclinecbfioor 5 whichis bounded byacimular flange 4. Immediately above the'floor 5 and hub 3 is a'stepbearing depening upwardly forreceiving andsteadying the lower end. ofthe vertical shaft 2'8 to 'WlllCll the abrading disk 26 is secured.-T-he' inclined floor 5=has at'itspovverportion-a drainage aperture-7through which all surplus-water may freely escape.

"The body or bowl His formed of Tfou-r curvedsections- 8 which,When-placed edge to e'd-ge, f0rm a-circular or cylindricalchamber which"fits down uponthe' upper edge of the circular flange-4 of: thehubhndfioor portion above referred to. These sections Soverlap as-at- 9'(Fig. 2)' and are secured together by screws 150. The lowerportions: 8"of the sections 8 are-sleeved down into the circular flange 4" (Fig.*4) and moreover; are secured in place thereon ;-by'=-bolts 12 extendingthrough lugs 11 (Figs'l and 2'). "The rear section i8 1 is formed Withan "inwardly eX- tending perforated avail to {form a spray chamber from-W-l1-ich --water freely passes through the aperture and into'th efbowl14L Whiohcontain-s the potatoes to be pared. The diagrammaticallyopposite section B is formed. With a discharging aperture 15provided-With. a threshold 17 having inward drainage aperture 18 topermit excess water running back into the space above "the floor Sandunder the rotating abrading'di'sk 26 (Fig.1). Azspout 19 extends'forvvard from'about the bottom and sides of the discharge opening 15and constitutes a discharge chute. A door 15 hinged at 16 to the upperpart of the section 8 provide-s a closure for the opening 15 and may beheld in closed position by the handle 20 pivoted to the door at 21 andadapted to engage a lug 22 on the threshold portion. By opening the door15 when the disk 26 is being rotated, the pared content will, undercentrifugal action, be discharged.

The upper part of the body or bowl 14 is provided with a cover 23 whichis flanged and fits to the sections 8 as shown in Fig. 4. This cover isprovided with a feeding aperture 24 having grooved side walls and inwhich a closure 25 is freely movable in a horizontal lane. When theslidable closure 25 is moved in a circular direction, it provides anelliptical opening 24 (Fig. 2) at the front por-.

tion of the machine and through which the charge of potatoes or othervegetables may be introduced. The closure 25 is so shaped that in effectitis hinged adjacent to the shaft 28 and center of the cover 23 and withits outer curved edge guided in the curved groove 24 (Figs. 2 and 4 Theinterior walls of the sections 8 are formed with abrading material suchas corundumsprinkled in the molds in which. the sections 8 are cast soas to become attached to the iron. The abrading surface may be of anyother suitable substance and attached in any other manner, as I do notlimit myself in this respect. The rotatable abrading disk .26 is made ofmore or less dish-shape and with its upper surface 27 similarly providedwith corundum or other abrading material, as in the case of the bodysections 8. The disk 26 may be of uniform concavity as in Fig. 4, orprovided with irregular raised portions 26 of any desired shape aspreferred.

The shaft 28 is centered at its lower end in the step bearing 6 toprevent lateral displacement and extends upwardly through the cover 23and journaled in a bearing 33 on a frame 34 which is hinged at 35 to theupper ends of two frames 36 secured at their lower ends to the flange 4at the rear part of the machine. This frame 34 is provided with lateralarms 34 (Fig. 1) which rest upon the upper ends of the side brackets 42which also are firmly bolted to the flange 4 at 44 and may also bedetachably bolted to said brackets by bolts 43. In thismanner, the frame34 is firmly positioned during the operation of the machine, but byremoving the bolts 43 it may be swung upward for reasons now to bedescribed.

When the shaft 28 is in operative position (Fig. 4), it is secured atthe top to a bevel gear 37 between which and the top of the bearing 33is interposed ball or roller bearings 38 so that the shaft may be freelyrotated notwithstanding the weight of the parts. A collar 39 may besecured to the shaft 28 by a set screw below the bearing 33 to preventthe shaft and gear lifting. An electric motor 40 is bolted to the frame34 above the hinged portions 35 and is provided with a small bevel gear41 which meshes with the large gear 37 (Fig. 4) and by which it isdriven.

The motor 40 is enclosed within a casing 48 also secured to the frame 34and this casing may extend laterally in a fixed portion 45 and in ahinged portion 46. These portions 45 and 46 form a box enclosing thegears 37 and 41 andalso the ball bearing 38. When it is desired to oilthe gears or bearings, the case part '46 is lifted upward and swungabout its hinges 47. It will be understood that in this manner the motorand driving mechanism are protected against injury from moisture.

The manner in which the disk 26 is suspended upon the shaft 28 is bestshown in vvFigs. 4 and 5, from which it will be seen that the disk isprovided on its under side with a hub 29 through which the shaftextends. This hub has upwardly extending side notches or. recesses 31which receive the ends of a transverse pin 30 which extends through theshaft. In this manner, the disk is made to rotate with the shaft but byraising the disk, the pin 30 may be removed and the shaft withdrawn fromthe, disk. When this is being done, both the shaft and disk are raisedpart way up throughthe body or bowl 14 so as to permit access below thedisk. To permit the raising of the shaft 28, the collar 39 must beloosened, the case part'46 raised and the gear 37 and shaft 28 lifted.In this waythe shaft may be lifted entirely clear of the machine. Thedisk 26 may be sustained wholly by the shaft 28 and its ball bearings 38or, if desired, the hub 29 of the disk may lightly rest on the hubportion of the step bearings 6. It is desirable, however, to rely on theball bearings as the sustaining means so that the machine may be runwith the least power. Vhen the shaft 28 is removed, the frame 34 may beswung upward and back, the cover 23 removed and the disk lifted out Inassembling, the reverse order is employed.

The water is supplied to the machine in the following manner. A pipe 51connected through a union 52 with a plate which seals the spray chamber4-9 and by which water is sprayed upon the materials within the bowl 14.A branch pipe 54 delivers water to a horizontal nozzle pipe 55terminating in a curved spraypipe 56 arranged in the space below thedisk and above the floor 5 which insures thorough washing of wastematter including the peelings from the machine through'the waste pipe 7.

The hub 29 of the disk 26 may have an annular apron 32 about it toshield the bearing 6 from p'eelings and excess moisture. In Fig.

6, I haveqshownia:modified constructionifor supporting the "disk-26 uponthe shaft 28. In .this construetion :there is provided: a collar "29secured'to' the shaft bya set screw 30. [l -his collarisprovided on thelower part with the apron and-at the upper part with lugs 30-.corresponding to 'the endsof the pinRO in 5. This: constructionobviates the neeessit-y of reinovingzthe pin 30.

It will now be apparent thatI have devised a novel and usefulcohstruction which embodies the features of advantage enumerated asdesirable, and while I have in the present instance shown and describedthe preferred embodiment thereof which has been found in practice togive satisfactory and reliable results, it is to be understood that I donot restrict myself to the details, as the same are susceptible ofmodification in various particulars without departing from the spirit orscope of the invention.
